STAMPING-MACHINE.

Specification of Letters Patent.

Patented Dec. 38, 1913.

Application filed May 29, 1913. Serial No. 770,674.

To all whom it may concern:

Be it known that I, FRANK M. MAHOOD, a citizen of the United States,residing at Roanoke, in the county of Roanoke and State of Virginia,have invented certain new and useful Improvements in Stamping-Machines,of which the following is a specification.

The object of my invention is to provide a convenient means for printingor stamping small papers such as vouchers, checks, etc, with whichobject in View it consists of the arrangements of elements ashereinafter described and finally claimed.

In the drawings, Figure 1 shows a transverse section of my invention,Fig. 2 a longitudinal section of the same, and Fig. 3 a longitudinalsection with the main feed roller depressed for shifting the type rollercarriage. Fig. 4 shows a transverse section of the type roller, and Fig.5 a longitudinal section of the same. Fig. 6 shows an end elevation ofmy invention attached to an ordinary adding or listing machine, and Fig.7 is an elevation of the opposite end, showing the operating mechanism.

Referring to the drawings in which like parts are represented by thesame reference numbers wherever they occur, 1 represents a main feedroller journaled at the ends 2 and 3 in the depending legs of a presserbar 4:. This presser bar 4 is supported on springs 5 and 6 for a purposewhich will be hereinafter stated.

Bearing on the main feed roller is a type roller 7. This type roller 7is made to shift freely along a shaft 8 which, in the drawings, is shownsquare. This shaft, however, may be of any shape or design that willallow the type roller to shift freely and at the same time serve torevolve the type roller when the shaft 8 is revolved. The type roller 7may be of any suitable design, but is made preferably as shown in detailin Figs. 4 and 5, which show the type roller as being composed of a typeholding block 52 of substantially U-shaped cross section, into which isset the type 53. The body of this type roller 7 is composed of twosections 54- and 55, divided transversely of the axis of the roller. Ascrew or pin 56 and a spring 57 hold the two sections 51 and 55together, thereby clamping the type block 52 between the circular heads58 and 59 of the sections of the type roller body. The portions of thesections of the type roller body over the type roller body in case thespring 57 fails to clamp the parts sufficiently, I provide a keyingextension 61 on each of the circular heads of the sections 54: and 55 ofthe type roller body, with a corresponding portion cut away at each endof the type block.

Extending through a slot 9 in the top of a case 10 is a type rollercarriage 11, which is made in the form of a yoke with depending arms 12.The ends of these depending arms are cut out in a semi-circular shape at13 to embrace short hubs 1 1 on the ends of the type roller 7. At 15 isan inking roller journaled in the depending arms 12 of the type rollercarriage at 16 and 17, and hearing on the face of the type in the typeroller 7. At the ends of the inking roller 15 are small collars 18adapted to roll on similarly disposed collars 19 on the type roller 7.The purpose of these collars is to prevent the inking roller fromdepositing ink on any portion of the type roller except the face of thetype, while at the same time, the collars 18 being slightly removed fromthe main body of the inking roller 15, there is little possibility ofink being carried on the faces of these collars 18 to the collars 19 ofthe type roller. The collars 19 drive the main feed roller 1 and theinking roller 15 when the type roller 7 is revolved, and the saidcollars 19 together with the main feed roller 1, propel the sheet ofpaper or other matter to be printed through the machine.

As previously stated the top of the type roller carriage 11 extendsthrough a slot 9 in the top of the case 10. Through this top portion ofthe type roller carriage is a vertically disposed'slot 20, through whichextends a lever 21 pivoted to the type roller carriage 11 at 22. To thelower end of the lever 21 and integral with the same is a housing 23carrying rollers 21 and 25, which are adapted to roll on the horizontalportion of the presser bar 1. The sides of the housing 23 extendslightly below the horizontal portion of the presser bar 41, forming aguide. For securing the type roller carriage 11 in the slot 9 I providean oblong cap 26, which is secured to the top of the type rollercarriag'e 11 by any suitable means.

Secured to the shaft 8 and located preferably between the walls 26 and27 of the case 10 is a .small gear pinion 28. This small gear pinionengages a gear wheel 29 which is secured to a short shaft 30, the innerend of which is journaled in the wall 26 and the outer end, passingthrough the wall 27, carries the operating mechanism as follows: Theratchet wheels 31 and 32, which are so disposed as to operate in reversedirections, are secured to the end of the shaft 30. These ratchet wheelsmay be made in one piece or they may be made separate and beindividually secured to the shaft 30. Pivoted loosely around the shaft30 is the main operating lever 33, to which is pivoted, at 3st, aratchet pawl 35, adapted to engage the teeth of the ratchet wheel 32. Aspring 36 is provided to pull the pawl 35 into engagement with theratchet wheel 32. A pawl 37, pivoted to the outer wall 27 of the case 10at 38, is provided for the ratchet wheel 31. A pin atO is fixed to thelever 33, so that when the lever 33 is raised the pin d0 will strike thepawl 37, disengaging it from its position on the ratchet wheel 31. Theupward movement of the lever 33 will be limited by the stop 39 on thecase 10. hen the lever '33 is moved downwardly the ratchet wheel 32 willbe revolved for a portion of a revolution until stopped bya tooth of theratchet wheel 31 coming into position against the pawl 37. This port-ionof a revolution will, through the gears 29 and 28, revolve the typeroller and through this the other rollers as previously described. Themachine as shown in the drawings is designed to give one completerevolution of the type roller for each portion of a revolution of theratchet wheel 32 as limited by one tooth of the ratchet wheel 31. Ininstances where a greater or less amount of revolution of the. typeroller is desired for each movement of the main operating lever 33, theratio of the gears 28 and 29 may be changed.

The main operating lever 33 may be actuated by any suitable means, as byhand or power. At 411 is shown a rod for connection to a suitable part12 of an adding or listing machine of the type to which it is intendedparticularly to apply this invention. Fig. 6 of the drawings shows myinvention applied directly to this adding or listing machine, it beingplaced on the table or shelf 43 of the said adding or listing machine.

At 4% I provide a table or shelf for convenience in handling the matterto be passed through the machine, which matter is fed by hand through anopening 455 in the case 10.

A specific instance of the use of my invention in conjunction with anadding or listing machine is to be seen in the operation of listing andadding checks and other items in the routine work of a bank, where it isnecessary to stamp the banks indorsement on the back of each item. Theitems to be treated are stacked face upward on the table of myinvention. As the amount of each item is placed in the adding machine,the item itself is fed face downward into the machine of my invention.hen the mechanism of the adding machine is actuated to complete theadding and listing the item is simultaneously propelled through mymachine and deposited, with the banks indorsement on the back thereof,in the drawer provided for that purpose.

At a6 is a guide to assist in entering the matter to be printed betweenthe rollers 1 and 7.

At 47 I provide a drawer for receiving the matter after it has passedthrough the machine as already described.

The entire top portion of the case 10 is hinged at 48, so that it may beswung back as shown in dotted lines at 4:9, for readily changing thetype in the type roller or for other purposes. The rear portion of thecase 10 is hinged at 50, so that it may be opened as shown in dottedlines at 51 to inspect the machine or for other purposes.

As previously stated the presser bar 4t is supported at either end onthe springs 5 and 6. The purpose of this is as follows: When it isdesired to shift the position of the type roller on the shaft 8, inorder to make the imprint of the type at any desired position on thematter to be stamped, the knob-shaped top of the lever 21 is pushed asto the left in Fig. 3, when the lever 21, pivoting about 22 willslightly depress the roller 24 and rise the roller 25. This, in turn,will force the one depending leg of the presser bar 4 down on the spring5, compressing this spring and lowering the roller 1. This relieves thefriction between the roller 1 and the type roller 7 so that the typeroller carriage 11 may be freely shifted. In shifting to the right, ofcourse, the results are the same, the spring 6 at the opposite end ofthe machine being compressed.

Having thus described my invention what 1 claim and desire to secure byLetters Pattype roller and said main feed roller, substantially asdescribed.
